Numerical analyses for mass transfer from a binary solution drop with surface mass ejection or suction are made by using a finite difference method for diagonal Schmidt number Sc-AA = 1-3, Sc-RB = 1-2, Reynolds number Re-p = 10-100 and surface mass ejection or suction ratios <()over bar> = -0.23 similar to0.21 at nondiagonal Schmidt number Sc-AB = 5, Sc-BA = 5 and driving force ratios Delta omega (B)/Delta omega (A) = 5. The average diffusion fluxes of a binary solution drop after due consideration of the effect of interaction between diffusion fluxes are affected by Re-p, Sc-AA and <()over bar>. A new correlation for the average diffusion fluxes of a binary solution drop with surface mass ejection or suction is proposed in terms of multicomponent transfer numbers.
